Unambiguous fermionic-string amplitudes.

چکیده
We show how to treat boundary divergences in heterotic string theory covariantly and unambiguously. The method applies even to theories with nonvanishing tadpoles; in this case the Fischler-Susskind mechanism sufficies to ensure well defined answers. Also n-point functions are well defined with no special string-tension renormalizations. As an example we find the loop corrections to the linearized background equations of motion for the O(16)×O(16) string needed to give unambiguous, finite scattering amplitudes. No splitting or projection of supermoduli space is needed.

Integration Measure and Spectral Flow in the Critical N=2 String
I present the moduli space of the (2+2)-dimensional critical closed fermionic string with two world-sheet supersymmetries. The integration of fermionic and Maxwell moduli in the presence of punctures yields the string measure for n-point amplitudes at arbitrary genus and instanton number. Generalized picture-changing and spectral-flow operators emerge, connecting different instanton sectors. Tr...
متن کاملBracket Symmetries of the Classical N=1 String
We show that it is possible to extend Moore’s analysis of the classical scattering amplitudes of the bosonic string to those of the N=1 superstring. Using the bracket relations we are able to show that all possible amplitudes involving both bosonic and fermionic string states at arbitrary mass levels can be expressed in terms of amplitudes involving only massless states. A slight generalization...
متن کاملOn the Compton Scattering in String Theory
We explicitly compute the Compton amplitude for the scattering of a photon and a (massless) “electron/positron” at tree level and one loop, in a four-dimensional fermionic heterotic string model. We comment on the relationship between the amplitudes we compute in string theory and the corresponding ones in field theory. CERN-TH/97-212 August, 1997
متن کاملSpace - Time Supersymmetry of Extended Fermionic Strings in 2 + 2 Dimensions Sergei
The N = 2 fermionic string theory is revisited in light of its recently proposed equivalence to the non-compact N = 4 fermionic string model. The issues of spacetime Lorentz covariance and supersymmetry for the BRST quantized N = 2 strings living in uncompactified 2+2 dimensions are discussed. The equivalent local quantum supersymmetric field theory appears to be the most transparent way to rep...
متن کاملMulticritical Matrix-Vector Models of Quantum Orbifold Geometry
We construct bosonic and fermionic matrix-vector models which describe orbifolded string worldsheets at a limit in which the dimension of the vector space and the matrix order are taken to infinity. We evaluate tree-level one-loop or multiloop amplitudes of these string worldsheets by means of Schwinger–Dyson equations and derive their expressions at the multicritical points. Some of these ampl...
